The solution
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Move the summands with the other variables
from left part to right part, we given:
$$12 x = 11 y + 20$$
Divide both parts of the equation by 12
We get the answer: x = 5/3 + 11*y/12
12*x-11*y = 20
Looking for similar summands in the left part:
-11*y + 12*x = 20
Move the summands with the other variables
from left part to right part, we given:
$$12 x = 11 y + 20$$
Divide both parts of the equation by 12
x = 20 + 11*y / (12)
We get the answer: x = 5/3 + 11*y/12

$$x_{1} = \frac{11 \operatorname{re}{\left(y\right)}}{12} + \frac{11 i \operatorname{im}{\left(y\right)}}{12} + \frac{5}{3}$$
x1 = 11*re(y)/12 + 11*i*im(y)/12 + 5/3
